Description

Technical Field

[0001] This utility model belongs to the field of sock technology, and in particular relates to a novel type of heat-generating sock. Background Technology

[0002] In low-temperature environments, heated socks, with their active heating properties, have become an important warming item for daily outings and outdoor work. They generate heat by connecting to a power source via an electric cord, continuously providing warmth to the feet, effectively resisting the cold, and meeting users' core need for warm feet.

[0003] However, current traditional heated socks have significant flaws in the design and installation of the power cord, severely impacting user experience and product lifespan. Firstly, the power cord in traditional heated socks is often sewn directly into the sock fabric. To prevent breakage during wear, a considerable amount of slack is required. This excess cord easily tangles and accumulates during wear, increasing the difficulty and time-consuming process, and causing a foreign body sensation after wearing, affecting foot comfort. Secondly, the exposed and unprotected power cord is susceptible to friction, pulling, or detergent corrosion during daily wear, washing, and storage. This damages the outer sheath and exposes the internal wires, leading to unstable heating function, short circuits, and electrical leaks. This significantly shortens the safe lifespan of the heated socks, increases replacement costs, and fails to meet users' dual needs for convenience and safety in heated socks. Utility Model Content

[0004] This utility model provides a novel type of heated sock to solve the problems in the prior art.

[0005] The present invention adopts the following technical solution: a novel heated sock, comprising a sock leg, a sock body, and a sock sole, wherein a heating wire is provided inside the sock sole, and a connecting wire is provided on the heating wire; an elastic strip is provided on the inner side wall of the sock leg, and the connecting wire is sewn onto the elastic strip to form a curved section; the upper part of the connecting wire extends from the top of the sock leg to the outside, and a plug is provided on the connecting wire.

[0006] In a further technical solution, the curved section is corrugated in both the upper and lower parts.

[0007] A further technical solution is that a power switch connected to a connecting wire is provided on the outer wall of the sock.

[0008] In a further technical solution, the elastic band is sewn onto the inner sidewall of the sock along the length of the sock.

[0009] In a further technical solution, the sock sole has a double-layer structure, and the heating wire is located in the middle of the double-layer structure.

[0010] In a further technical solution, the heating wire is evenly sewn inside the sole of the sock.

[0011] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0012] This invention employs a "rubber band fixing + bending section allowance" design, which avoids redundant accumulation of the wires due to lack of fixation and eliminates the need for excessively long wires. When worn, the wires fit snugly against the inner wall of the sock, preventing protrusions or tangling around the foot, significantly reducing discomfort and improving comfort and convenience, while shortening wear time. The rubber band fixing of the connecting wires reduces friction between the wires and the sock fabric or clothing such as trouser legs. Simultaneously, the bending section cushions tensile forces, reducing the probability of wire insulation damage and exposed wire cores. With the risk of exposed wire cores reduced, safety hazards such as short circuits and leakage are also decreased, extending the safe usage time of the heated socks and lowering the cost of replacement due to product damage.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The following detailed description, in conjunction with the accompanying drawings, illustrates the technical solution of a novel heated sock provided by various embodiments of this utility model.

[0024] Reference Figures 1 to 6 As shown, this utility model embodiment provides a novel heated sock, including a sock leg 1, a sock body 2, and a sock sole 3. The sock sole 3 is provided with a heating wire 4, and a connecting wire 5 is provided on the heating wire 4. An elastic strip 6 is provided on the inner side wall of the sock leg 1. The connecting wire 5 is sewn onto the elastic strip 6 to form a curved section. The upper part of the connecting wire 5 extends from the top of the sock leg 1 to the outside. A plug 8 is provided on the connecting wire 5.

[0025] First, the sock sole 3 serves as the core area for heat output. The built-in heating wire 4 is connected to an external power source via a connecting wire 5 and a plug 8 to form a closed circuit. When the plug 8 is connected to the power source, the current is transmitted to the heating wire 4 along the connecting wire 5. The heating wire 4 converts electrical energy into heat energy. Since the heating wire 4 is located in the sock sole 3, it can directly provide targeted heat to the feet, especially the soles and heels that are prone to cold.

[0026] Secondly, the connecting wire 5 is not randomly arranged, but forms a curved section on the elastic strip 6 on the inner wall of the sock 1. The elastic strip 6 itself is elastic and can deform synchronously with the expansion and contraction of the sock 1, such as the stretching of the sock 1 when the user wears it or the slight deformation when walking. The design of the curved section provides "elastic margin" for the connecting wire 5, preventing the wire from being directly pulled when the sock 1 expands and contracts. At the same time, the elastic strip 6 physically fixes the wire, preventing the wire from sliding or getting tangled inside the sock 1.

[0027] This invention utilizes a "fixed elastic band 6 + curved section allowance" design, which avoids redundant accumulation of the wires due to lack of fixation and eliminates the need for excessively long wires. When worn, the wires conform to the inner wall of the sock 1, preventing protrusions or tangling on the foot, significantly reducing discomfort and improving comfort and convenience, while shortening wear time. The connecting wire 5 is fixed by the elastic band 6, reducing friction between the wires and the sock body 2 fabric or clothing such as trouser legs. Simultaneously, the curved section buffers tensile force, reducing the probability of wire insulation damage and exposed wire cores. With reduced risk of exposed wire cores, safety hazards such as short circuits and leakage are also reduced, extending the safe usage time of the heated socks and lowering the cost of replacement due to product damage.

[0028] Specifically, the curved section has an upper and lower corrugated shape.

[0029] When a user wears heated socks, the sock leg 1 undergoes longitudinal (vertical) stretching deformation due to differences in leg thickness or leg movements during walking, such as knee bending and tiptoeing. At this time, the upper and lower corrugated curved sections can simultaneously "expand" or "contract" along the stretching direction of the sock leg 1. The change in the distance between the crests and troughs of the corrugations during stretching provides more ample longitudinal movement margin for the conductor, rather than the "one-way buffering" of the simple curved section in the basic embodiment. Simultaneously, the corrugated structure increases the contact area between the conductor and the elastic band 6, resulting in a more stable fixation and preventing the conductor from slipping off the elastic band 6 during the buffering process. Compared to existing technologies, the buffering direction of the upper and lower corrugated curved sections more closely matches the actual stretching direction of the sock leg 1, better handling the dynamic deformation of the sock leg 1 during daily activities, further reducing the tensile force on the conductor and lowering the risk of conductor breakage, making it especially suitable for users who frequently walk or exercise. The corrugated structure makes the wire and elastic band 6 more securely fixed. Even during vigorous activities, such as brisk walking or jogging outdoors, the wire will not slip inside the sock 1, avoiding the local foreign body sensation caused by wire displacement and improving wearing stability and comfort.

[0030] Specifically, a power switch 7 connected to the connecting wire 5 is provided on the outer wall of the sock 1. The power switch 7 is usually located in the upper part of the sock 1 for easy operation by the user's hand.

[0031] A power switch 7 is added and connected in series with the connecting wire 5 to form a complete controllable circuit consisting of "power supply - plug 8 - power switch 7 - connecting wire 5 - heating wire 4 - power supply". After wearing the device, if the user needs to activate the heating function, they simply close the power switch 7, the circuit is completed, and the heating wire 4 heats up. If the user needs to pause the heating function, such as when entering a warm room, they can directly disconnect the power switch 7, the circuit is broken, and the heating wire 4 stops working, eliminating the need for frequent plugging and unplugging of the plug 8. Furthermore, the power switch 7 is a waterproof push-button power switch to prevent water damage during cleaning.

[0032] Specifically, the elastic band 6 is sewn along the length of the sock leg 1 onto the inner sidewall of the sock leg 1. When the sock leg 1 stretches or contracts, the elastic band 6 causes the guide wire to deform synchronously, preventing relative friction or pulling between the guide wire and the sock leg 1. The elastic band 6 fits completely against the inner sidewall of the sock leg 1, and the connecting guide wire 5 is fixed to the elastic band 6 with intervals, without any excess protrusions or loose parts. This prevents friction against the leg skin during wear, further reducing the feeling of foreign objects and conforming to ergonomic design.

[0033] Specifically, the sock sole 3 has a double-layer structure, with the heating wire 4 located in the middle of the double-layer structure. The inner layer is made of skin-friendly cotton fabric, and the outer layer is made of wear-resistant nylon fabric. During operation, the heat generated by the heating wire 4 is transferred to the foot through the inner skin-friendly fabric, while the outer wear-resistant fabric provides protection, preventing the heating wire 4 from being damaged by friction between the foot and the ground or shoes. At the same time, the double-layer fabric forms a certain heat insulation space, reducing heat loss to the external environment and improving heat utilization.

[0034] Specifically, the heating wire 4 is evenly sewn inside the sock sole 3. The heating wire 4 is adapted to the shape of the sock sole 3, so that all areas of the sock sole 3 can receive appropriate heat, improving the overall warmth retention effect and better meeting the physiological warmth needs of the feet.

[0035] The heating wire 4 is equipped with a temperature control module (refer to Chinese patent application number CN202121874785.7). When the temperature of the heating wire 7 exceeds 45°C, it automatically cuts off the power to avoid overheating and burns. The plug 8 is compatible with 5V / 2A power supply to prevent high voltage from burning out the heating wire 4.

[0036] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
